Debris-resistant friction-ring stem casters each have a thread guard that prevents thread and debris from getting inside the caster and damaging or contaminating it. This helps extend the life of the casters when used on carts and equipment in dusty or dirty environments such as laundry rooms, textile factories, offices, retail stores, schools, and government buildings. The casters also have sealed precision ball bearings in their wheels that provide smooth, quiet rolling and prevent dirt and debris from entering the bearing and damaging it, and they have double ball swivel bearings that allow them to swivel smoothly.

General purpose friction-ring stem casters are used on carts, furniture, storage cabinets, storage bins, display stands, retail fixtures, and other equipment in a wide variety of institutional and industrial settings. The casters have double ball swivel bearings that allow them to swivel smoothly.

NSF-listed sanitary friction-ring stem casters are built to satisfy the National Sanitation Foundation's (NSF) rigorous testing requirements for casters that are used in environments where they will be exposed to frequent washdowns, oils, or chemicals. They are used in food-service areas, food-manufacturing facilities, cleanrooms, and similar environments where sanitary conditions must be maintained. The casters have double ball swivel bearings that allow them to swivel smoothly.

Total-locking friction-ring stem casters each have a total-lock brake that can be engaged to prevent the caster's wheel and swivel mechanism from moving. Sometimes called scaffold casters, these casters are used on light-duty scaffolding that must be kept stable and immobilized when people are climbing and working on it. The casters won't roll or turn unexpectedly, which can help prevent injuries. They are easier to remove and replace than stem casters that are secured to scaffolding using bolts or pins. Total-locking friction-ring casters are used on light-duty scaffolding in janitorial, maintenance, painting, electrical, and construction applications.

Low-profile friction-ring stem casters each have a single small-diameter wide wheel. They can be mounted onto equipment that must be kept low to the ground, such as business machines, vending machines, store fixtures, lab equipment, refrigeration units, dollies, and server cabinets. The casters have a low center of gravity that helps keep the equipment stable while rolling, and their low-profile design helps make them inconspicuous when installed. They have zinc-plated steel frames and double ball swivel bearings that allow the caster to swivel smoothly.

These friction-ring stem caster kits come with multiple casters and are used for applications where all the casters on a piece of office furniture or equipment need to be replaced. These casters are installed on chairs, carts, fixtures, and similar items used in environments where the casters won't be exposed to heavy loads, chemicals, liquids, or high temperatures, such as offices and retail settings. Soft-wheel casters are less likely to damage hard tile or wood floors than hard-wheel casters, and hard-wheel casters won't grab or snag carpets. Each kit's load rating is the sum of the load ratings for all the casters in the kit. For example, if each caster in the kit has a load rating of 200 lbs. and there are four casters in the kit, then the load rating for the kit will be 800 lbs.

These friction-ring stem casters are installed on chairs, carts, fixtures, and other office furniture and equipment. They are suitable for use in offices, retail settings, and other environments where the casters won't be exposed to heavy loads, chemicals, liquids, or high temperatures. Soft-wheel casters are less likely to damage hard tile or wood floors than hard-wheel casters, and hard-wheel casters won't grab or snag carpets.

These friction-ring stem casters each have two wheels, which reduces the friction between the floor and the wheels (also known as scrubbing) and allows the casters to swivel more easily than single-wheel low-profile friction-ring casters. The casters have small-diameter wide wheels and can be mounted onto equipment that must be kept low to the ground, such as business machines, vending machines, store fixtures, lab equipment, dollies, and server cabinets. The casters have a low center of gravity that helps keep the equipment stable while rolling, and their low-profile design helps make them inconspicuous when installed. They have zinc-plated steel frames and double ball swivel bearings that allow the caster to swivel smoothly.

These friction-ring stem casters are made from stainless steel and resist corrosion when exposed to water and chemicals. They have a smooth, polished finish that eases cleanup, and they have thread guards that stop debris from getting into the casters and damaging them. The casters' wheels are impregnated with an antimicrobial compound that prevents microbes from growing on the wheels and causing odors or degrading the casters. The wheels are nonmarking, which prevents damage to floors, and they have precision ball bearings for smooth, quiet rolling. These casters are used on carts and equipment in locations that must maintain high standards of cleanliness, such as medical offices, laboratories, pharmaceutical plants, cleanrooms, and food-service facilities.

These friction-ring stem casters have sealed precision ball bearings in their swivel raceways and wheels that do not need to be routinely greased. This reduces time spent on maintenance and helps extend the life of the casters. These casters roll more quietly than other types of friction-ring stem casters. The casters' nylon frames resist chemicals and corrosion and weigh less than metal frames. They are used on carts or other equipment in settings where the equipment will be moved frequently and may be exposed to water or chemicals, such as medical facilities, hospitality and retail establishments, laboratories, and food-service areas. The casters have nonmarking wheels that prevent damage to floors, and they have thread guards that keep dirt and debris from getting into the casters and damaging them.

These friction-ring stem casters have bearings that provide smooth, quiet rolling, which helps reduce noise that can disturb patients in medical settings, such as hospitals, rehabilitation centers, pharmacies, and laboratories. They can be mounted to beds, gurneys, IV poles, maintenance carts, food-service equipment, and other items used in these settings. The casters' nonmarking wheels have soft treads that help prevent damage to floors. The casters also have thread guards that keep thread and other debris from getting into the casters and damaging or contaminating them.

Wall-protecting friction-ring stem casters have rubber rings (also called donut bumpers) that protect walls and other vertical surfaces from damage if the equipment the casters are installed on collides with the walls or surfaces. The bumpers also absorb some of the impact in the event of a collision to protect sensitive materials being transported on the equipment from shock and vibration. These casters can be mounted to carts and other equipment in offices, retail stores, laboratories, cleanrooms, and warehouses.
